What MDM configuration must an engineer consider when traveling with a corporate-owned mobile device that prohibits personal data?

Containerization is the correct choice in this scenario because it refers to a method of separating corporate data from personal data on a mobile device. By implementing containerization, the corporate-owned device can maintain a secure, controlled environment for work-related applications and data, while also ensuring that any personal data remains outside of that secure area. This configuration is crucial when traveling with corporate devices, as it prevents unauthorized access to sensitive information and helps the company comply with policies that prohibit the mixing of personal and corporate data.

In this context, while screen locks provide a basic layer of security by requiring authentication to access the device, they do not specifically address the separation of data types as containerization does. Application management, although vital for controlling which apps can be installed or used, does not inherently create a barrier between personal and corporate data. Geofencing involves using GPS or RFID to create virtual boundaries but does not impact the data segregation needed when prohibiting personal data on a corporate device. Therefore, containerization emerges as the most relevant configuration for ensuring that corporate-owned mobile devices are secure and compliant with data protection policies while in use.
